JIETHOD OF PRESERVING LIVE FISH To all Ywhom it indy concern.'-Y

Be it known that I, FRIEDRICH KLEIN- sonmnfr, a subject of the King of Prussia,-

and resident of Bucharest, Roumania, have invented new and useful Improvements 1n the Methods of Preserving Live Flsh During a Long Period of Transport or in Store, of

'methods heretofore used.

has led to the regeneration of the water mainly by injecting oxygen or'air. How- -ever, these improved methods of keeping fish alive during transportation, or in storage,

have not proved satisfactory, for the reason that the effect of theinjeetion of airor Oxygen is `of very short duration, making repeated renewals of the water necessary.

The purpose of m improved method is to keep the Water wellsatumted with oxygen and in a sufiiciently oxidized condition for respiration and to preserve the fish alive.

ccording to my invention, I regenerate the water containing the fish by continuously bringing it into contact with ozone; thereby supplying at all times a sufficient quantity of oxygen, the ozone, in some manner, neutralizing or destroyin .the respiration products eliminated from t e fish. As long as the water is regenerated by ozone in this manner the fish can be kept alive in it indefinitely.

Mv improved method, therefore, consist-s in filling tanks, or receptacles intended for receiving the fishto be reserved, with Water in which the fish have ived, and in continuouslysubjecting the water to the'action of ozone, whereby oxygen is continuously supplied thereto, suflicient in quantity to keep the water in the state favorable to the preservation of the fish; organic impurities being removed or Vretained in any desired way by surface filters. Vater continuously regenerated by the ozone, asphyxiation of the fish by carbon dioxid, es in former methods of preservation, is entirely obviated.

my method. it is necessary to keep the fish perfectly qrriet in the water. To this end, the temperature of the water containing the fish is kept very low; by which means the number of ish carried in one receptacle can also be greatly increased,` the ratio between the quantitj. of fish and the quant ityol' water beine` as high as 1:1. This means a considerab e decrease in the dead weight to be car;- ried as compared with the 'methods heretofore used, in which the ratio is about 1:5. double advantage is, therefore, adherent in .my new method; as not only is the time durino' which the sh can be kept alive practica ly unlimited, but the number of lishwhich can be carried in each tank is great-ly increased. l A

My method can be used on railroad cars, vessels, and nher means of transportation as Well as in fish markets and other places of 'storage'.`

along the irregular-broken lines' HII of Fig. The car eentains two compartments, one of which is used for the operatm'g means; the other containing a-water regenerating a paratus M, an sir-dryimr appara-tus E, am the ish tanks T. The latter compartment is provided with insulation in orde) to, keepthe temperature iov: by preventing thc radiation of heat into the compartment. The water regenerating apparatus M is closed and provided at its upper end with an openinv communicating` with the air duct 2. il the lower ortica of thc tower M, the ozone isV admittet by tree pipe 2', and still nearer the bottom of the zower a water discharge opening is provided, which isl connected by the pi e I with the pump P. The admission of tiie water is eected by a partial vacuum produced by the air pump L, by reason of the slight res rence to the incoming lair in the air filter E, hereinafter described. Outside air is diam into the towerV M by the air pump L, passing on its way through the d1ymg and nl* A113g apparatus E, to conduit 24 and the oz apparatus O, from which it is suppiied to the tower through the con duit 2'.

. Throtgr. -a branch of the conduit 2, the tower is continuously exhausted, and the gas L generation can befurtber utilized; by which mixture leeving said tower is deprived ,of its eer-bon dioxirl 1n any desired `manner as by pessing it through a receptacle containing substances adapted to absorb the cerbon i dioxid, .and is used tof'urtber cool `the air drawn in tli rough the conduit 2.' On accoun t ai the slight vacuum in the ltower the .water from the tanksT passes into it by e. pipe A, or in Sonie other similar manner, and, es already described, is finely divided sind distributed in the tower. As the ozonized air is supplied to the tower near the bottom, the water is sub'ectecl to its action during the time it is fallin the length of the tower.

Thus regenerate it is drawn o5 by Ineens of4 the pump P, and is returned through the pipe B andnozzles D to the tanks. 11 the top of each tank is a, filter F for reteining sediment and precipitates dicult to decompose. The gas mixture resulting from tbe weiterreduid for the further regeieretion of the' water, conducting the same througlithe conduits 2 and the pump L, the volurneo ozonized air drawn m by the ump beaute'- mtieelly regulated eccor ing to thedernend ferie eneretion. It has been found that the 'el er hevin Given off the cerbcn'dioxid l b I contains e larger amount of oxygen then bei'ore and therefore even better suited for. further use 1n regenerating the weter.-

A compressor K and surface condenser for condensing and licllu'efyn the ges for cooling the cer are provi( for operating the ozonizer is furnished by a. dynamo G connected to e transformer U,end the powerfor driving tb'edynarno and compreesor is obtained from an engine B.
